Beit known that I, WILLIAM R. RoTrrwnLL, a citizen of the United States,residing at the city of Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented certain new and useful Improvementsin Fountain-Pens, of'which the following is a specilication. A

My invention has relation to the provision of a fountain type of penwith a detachable device for not only clamping the pen within the barrelor holder for use, but also providing the necessary air-vent for the inkin the reservoir of the holder to permit of the antomatic flow or feedof the ink .in regulated quantity from the reservoir of the holder tothe pen along one surface of the device, whereby reliable working of thepen is uniformly insured; and in such connection my invention relates tothe particular construction and arrangement of the device forautomatically feeding, for holding the pen in required p0- sition in theholder, and for venting with air the ink in the reservoir of the holder,as hereinafter more fully described and claimed.

The nature and characteristic features of my invention will be morefully understood from the following description, taken in connectionwith the accompanying drawings, forming part hereof, in which- Figure lis longitudinal sectional view of a fountain-pen, showing the operativeparts as well as the device of my invention in elevation. Fig. 2 is avertical central sectional view of so much of a fountain type of pen aswill serve to illustrate the application of my invention thereto. Fig. 4is a transverse sectional view of the pen holder or barrel, and an underplan view of the pen and the device of my invention in application. Fig.4 is a crosssectional view through the barrel, pen, and device on thelinee 4 of Fig. 3; and Fig. 5 is a top or plan view of the detailconstruction of the automatic feeding, holding, and air-venting deviceof my said invention.

Referring to the drawings, A is the fountain-pen barrel within which thereservoir for ink is provided, and which barrel or holder may be of anyof the well-known types of such character of pens.

. :iisthepem which may bel-'ofl'any 'ordi-` nary type. n

' C isthe device of my invention, made of rubber, ber, papier-mch,orother preferred material capable of being bent under the influ- 5 5 enceof heat for causing the same to assume the required shape or conditionfor being adapted for use in connection with a pen and its holder orbarrel, so as to hold the pen snugly to place in the barrel orreservoir-holder A, and so .arranged as to supply the necessary amountof air to the ink in the barrel A to permit of the free ow or feed ofthe ink from the reservoir as required along one surface thereof to thepen B. This device C consists of a narrow oblong fiat strip c, slightlycurving upward from the rear portion to the tapering front blunt-pointedend c', as clearly illustrated in Figs. 2 and 5. The respective sides c2and c3 are preferably beveled off, as in Fig. 7o 5, to fit the undersurface of the pen, as illustrated in Fig. 3, and the top surface of thedevice is arranged so as to form with the pen in position in the holdera channel or way ci, so that when the device C is in operative position,as illustrated, for example, in Figs. l and 3, the ink will flow or befed automatically from the holder-reservoir A along the top surface ciof the device to the point of the pen B for writing by exerting a mildhand- 30 pressure on the holder.

The rear portion of the device C is 'bent either upward or downward ontothe main body portion of the device into preferably a coil c5, Figs. 1and 2. The under surface of 85 the coiled portion c5, at the respectiveedges, is beveled 0E, so as to snugly fit the holder, as clearlyillustrated in Figs. 3 and 4, and while the coiled portion forms a meansfor engaging with the sides or edges of the pen for snugly yetdetachably holding the pen in the barrel or holder it at' the same timefrom the under side permits of free ingress of air at c between thebarrel A and the coiled portion c5 of the device into the reservoir of95 the-pen barrel or holder, whereby as so arranged the 'iiow or feedautomatically of ink to the pen from the reservoir whenv the holder hasbeen caused to assume the required angle of inclination is alwaysinsured. 109

Having thus described the vnature and objects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is#

1. In a fountain-pen, a holder, a pen and a device, consisting of a flatstrip tapering to with the pen a channel or way, and the oppo site endformed into a coil having beveled sides, substantially as and for thepurposes described. Y

3. In a fountain-pen, a device consisting of a fiat narrow strip ofpliable material, one surface forming with the pen a channel or way, andthe rear of the device formed into a coil interposed between the pen andholder, y

substantially as and for the purposes described.

In testimony whereof I have hereunto set my signature in the presence oftwo subscribing witnesses.
